Ultra High Efficiency Water Heaters
eF Series® Standard Equipment Features:
Thermal Efficiency up to 99.1%—Fully condensing design.
Three Pass Flue System—The three pass flue system
keeps the hot combustion gases moving at a high velocity.
The combination of high turbulence and velocity causes an
enormous rate of heat transfer into the water.
Low NOx Premix Power Burner—Developed for the
eFSeries®, a turbulent flame shoots down the submerged
combustion chamber. This turbulence causes a thorough
mixing of the gas and air for optimum combustion and high
heat transfer efficiencies. — Far exceeds California
emission requirements.

Flexible Venting—The eF Series® can vent vertically or
horizontally with either 3" or 4" PVC, CPVC or ABS vent
pipe, and is approved for direct vent closed combustion
applications, or those applications that require inside air for
combustion. Foam Core pipe is permitted on the entire
venting system. The eF Series® is also approved for
unbalanced venting, which means the air intake pipe
doesn't have to be vented the same distance as the
exhaust.
(NOTE: Air intake cannot exceed exhaust by more than
30 feet.)

Model
Number

Submerged Combustion Chamber—Submerging the
combustion chamber in the center of the water storage
tank minimizes radiant heat loss and improves efficiency.

EF-100T-399

Non-CFC Foam Insulation—Surrounds the tank surface,
saving energy by retarding loss of heat.
Electronic Controls—Adjustable electronic thermostat for
control between 80°F and 180°F. The recycling Energy Cut
Off (ECO) shuts off all gas flow in an event of an overheat
condition.
Zero Inch Clearance—The eFSeries® jacket is cool to the
touch and is approved for zero inch clearance to
combustibles for unsurpassed installation flexibility.
Vitraglas® Lined Tank—Bradford White’s water heater
tanks are protected from the corrosive effects of hot water
by an exclusive ceramic porcelain-like coating. Our high
silica Vitraglas® lining provides a tough interior surface for
Bradford White’s water heater tanks.
Protective Magnesium Anode Rods—Employed to
provide an extra measure of corrosion protection for longer
life. Each eF heater has 4 anodes, except the EF-100T-399
which has 2 powered anode rods and one non-powered
anode rod.
Factory Installed Hydrojet® Sediment Reduction
System—Cold inlet sediment reduction device made of
stainless steel for increased durability. Helps prevent
sediment build up in tank.
Factory Installed Dielectric Fittings—All heaters equipped
with special water heater nipples for longer heater life. No
special dielectric fittings to buy.

Determining required vent length
1. Determine the total length of straight vent pipe (in feet)
required for both the intake and the exhaust.
2. Add 5 feet of venting for every 90˚ elbow.
3. Add 2 1⁄2 feet of venting for every 45˚ elbow.
4. Total vent length cannot exceed "Max Length" in the
above venting table.
5. Air intake cannot exceed exhaust by more than 30 feet
in any venting situation.
NOTICE: Do not include the 3" exhaust elbow or vent
terminals in determining maximum vent length.
Three year limited warranty on steel tank — Heavy
gauge steel automatically formed, rolled and welded to
assure a continuous seam for glass lining.
One year limited warranty on parts

eF Series® Optional Equipment Features:
Maxitrol Gas Pressure Regulating valve—Ensures
proper supply pressure to eF unit of 7" to 11" W.C.
(provided incoming pressure is between 1/2 and 2 psi).
This can be ordered as a separate part, or as part of
the heater. For the separate part, please use
p/n 243-45517-00 (not available for use with the
EF-100T-399).
Concentric Vent Terminal Kit—3" termination fitting
provides for only one exit opening through wall or roof
(p/n 239-44069-01).
NSF Compliance Kit—p/n 265-44542-04.

Ultra High Efficiency Water Heaters
All models are design certified by CSA International (formerly AGA/CGA) for up to 180°F (82°C) application as an Automatic
Storage Heater, and an Automatic Circulating Tank Heater.
As an Automatic Storage Heater, all models are complete self-contained water heating systems. It needs no separate
storage tank, pump, wiring or elaborate piping network. When equipped with a mixing valve, it will supply 180°F (82°C)
sanitizing and 140°F (60°C) general purpose hot water simultaneously. These models can be used either as a single unit or
as multiples connected in parallel.
Sample Specification
The water heater shall be a Bradford White model EF-_____ with a rated storage capacity of not less than _____ gallons/
liters, a minimum gas input of __________ BTU/hr, a minimum recovery of _____ GPH/LPH at 100°F (56°C) temperature rise,
and a Thermal Efficiency Rating of ____%. It shall be design certified by CSA International (formerly AGA and CGA) for
180°F (82°C) application, either with or without a separate storage tank. The tank shall be lined with Vitraglas® vitreous
enamel and shall have a bolted hand hole cleanout. The tank shall have four extruded magnesium anode rods installed in
separate head couplings (up to 300,000 BTU/hr input) or two powered anode rods and one extruded magnesium anode rod
(for 399,999 BTU/hr input). This water heater shall be equipped with stainless steel cold water inlet, Hydrojet® Sediment
Reduction System. The heater shall be insulated with Non-CFC foam. This water heater shall be equipped with an electronic
ignition system, an ASME rated T&P relief valve and a premix closed combustion system for direct venting using either 3"
(76mm) or 4" (102mm) PVC, CPVC or ABS vent pipe. (115V AC required). The water heater shall be factory assembled and
tested. The water heater shall be approved for zero inch clearance to combustibles. The control shall be an adjustable
electronic thermostat to any temperature up to 180°F (82°C). A recycling Energy Cut Off (E.C.O.) shuts off all gas in the
event of an overheat condition. The entire installation shall be made in compliance with state and local codes and
ordinances.
Dimensions and specifications subject to change without notice in accordance with our policy of continuous
product improvement.
